Mesh simplification qem

WebThis paper presents a fast mesh simplification algorithm that combined the half-edge data structure with modified quadric error metric (QEM). When half-edge structure is used, the adjacency queries between components of the mesh, such as vertices, faces and edges, can be quickly achieved and thus the run time is reduced remarkably. Webels or a multiresolution representation such as a progressive mesh [3]. 3.1 Aggregation. The primary benefit which we gain by utilizing general vertex pair contractions is the ability …
